“Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents.Tesla’s original circuits as well as most modern coils use a simple spark gap to excite oscillations in the tuned transformer. More sophisticated designs use transistor or thyristor switches oscillators to drive the resonant transformer. Miniature Tesla coil also does a same work but it does not produce as much high voltages. Now I am going to instruct how to make a miniature tesal coil with less number of components.
